You can learn a ton about Tim Cook just by looking at his favorited tweets

Apple CEO Tim Cook finally joined Twitter in September 2013, but while he only tweeted occasionally in his first year on the network, he's been much more active on the platform lately.

Aside from tweeting about Apple events, holidays, Apple products and social equality, Cook also actively favorites others' tweets. On Thursday, for example, Cook favorited a handful of tweets about Apple Pay becoming availble in the UK for the first time, which is good news for anyone using London's transportation systems.

We've rounded up some of Tim Cook's favorited tweets to give you a better idea of what Apple's CEO cares about.

First of all, Cook loves Duke, particularly Duke basketball. This makes sense considered he earned his MBA from Duke University's Fuqua School of Business some 27 years ago.

He also occasionally shows love for his other alma mater, Auburn University, where he graduated with a B.S. in industrial engineering in 1982.

Cook also cares a ton about equality. In October 2014, Cook came out as gay in an editorial for Bloomberg Businessweek. Since then, he has been very vocal about issues like marriage equality.

He also has a penchant for favoriting tweets about greatness, particularly in sports. Cook clearly has a love for history and a desire to motivate others.

Cook also loves — LOVES — tweets from Box CEO Aaron Levie.

He also favorites tweets from Pope Francis quite often.

And of course, Cook is constantly on the lookout for positive responses to Apple products, particularly the Apple Watch and new Apple Music service.
